15.3) In the previous problem, you drew the products for the phosphorylation of ADP reaction (shown below). Does that reacti require energy or release energy when it occurs? ANSWER: This reaction requires energy in order to occur. phosphoryl group O-P OH inorganic phosphate (P₁) the OCH₂ H H H H OH OH adenosine diphosphate (ADP) NH₂ + H+ O O =+++R O -OCH₂ H H O H OH OH adenosine triphosphate (ATP) H NH₂ + H₂O

15.3) In the previous problem, you drew the products for the phosphorylation of ADP reaction (shown below). Does that reaction require energy or release energy when it occurs? ANSWER: This reaction requires energy in order to occur. phosphoryl group OH inorganic phosphate (P₁) 0=2-0 O 0=4-'0 P-OCH₂ H H O H N H OH OH adenosine diphosphate (ADP) NH₂ + H+ fol O-P-O O -OCH₂ H H O H N OH OH adenosine triphosphate (ATP) H NH₂ + H₂O EXPLANATION: Adding a phosphoryl group to ADP in order to form ATP requires energy. The positive value of AG for this reaction (7300 Joules per mole of ADP) indicates that the reaction requires energy in order to occur. This reaction will not occur spontaneously unless external energy is provided. Catabolic metabolic pathways often use the energy contained in food to drive the transfer of phosphoryl groups to ADP, thereby forming ATP.
